Federal Signal Model EWP Series ECHO Intercom Stations provide safe and efficient two-way voice communications in ECHO Digital Intercom Systems. 

The EWP Series ECHO station provides instantaneous high-speed connections and clear, crisp digital voice quality.  Each station offers single-button all call, priority emergency paging, group paging, speed dial, conference call, and relay output. 

Any station can call any other station(s) in an ECHO Digital Intercom System.  With the headset or gooseneck microphone options, each is capable of hands-free voice communication.  Because the ECHO Digital Central Exchange provides 30 channels of simultaneous communication, calls are processed and connected immediately without dial tone or delay. 

The Station keypad is designed to provide tactile and audible feedback (via external powered loudspeaker) for a positive activation.  Each station may be programmed for four levels of privacy for receiving calls;  non-private, semi-private, full privacy and do-not-disturb.  Volume for voice and signal levels are easily adjusted on the keypad. 

Each Station is constructed of heavy duty glass reinforced polyester (GRP), equipped with a weatherproof keypad, and are rated for use in IP66 dust- and water-tight applications.

Stations can be ordered with polyurethane  curly cord, stainless steel cord, headset (with optional extension), stubby microphone or gooseneck microphone.
